Entwickler startet zwei L402-APIs, die KI-Agenten direkt per Micropayment nutzen können
KI-Agenten scheitern oft daran, dass API-Zugänge klassische Infrastructure wie Signups, API-Keys und Kreditkarten erfordern. Mit L402 ist die Zahlung selbst der Zugriffsnachweis. Der Entwickler hat daraufhin zwei APIs gebaut, unter anderem für aufbereitete Daten ab 10 Sats.
AI agents can write code, browse the web and run tools — but the moment they need to pay for an API, the flow collapses into human infrastructure: signups, API keys, credit cards, monthly plans.
L402 fixes that. The payment is the credential. So I built two production-light APIs that any agent (or human) can consume autonomously over Bitcoin Lightning, and put them live:
No accounts. No keys. You call, you get a 402, you pay the Lightning invoice, you retry with the proof, you get the data.
The middleware is protocol-standard, not a custom hack:
It works out of the box with standard tooling like Lightning Labs' lnget — point it at an endpoint and the pay-and-retry cycle is automatic.
Discovery is built in too: a machine-readable manifest at /.well-known/l402.json, public pricing at /pricing, interactive OpenAPI docs at /docs, and the service announces itself on Nostr with NIP-89 handler events (kind 31990) so agents can find it without me doing marketing.
Under the hood: FastAPI, an in-memory TTL cache (repeat calls are cheap), and live upstream data — nothing in the forensic report is mocked.
The cheapest call costs 10 sats — less than a cent. If you're building agents, trading bots or L402 tooling, I'd genuinely love for you to:
Docs and manifest are public, the code structure is a standard FastAPI service, and the paywall answers with a real invoice from a real wallet. The machine economy needs services that are actually buyable by machines — this is my first one.
